The recent Ukraine war shows that soldiers lifes are cheap - according to commanders.

So many soldiers on both sides died because of really dumb commander decisions, missing kit, political needs, that worrying about CPU errors is truly way way down the list.

At the tactical level, of course that what you're saying is true, but the big Ukrainian counter-offensive from last year had been preceded by lots and lots of allusions made to "war games simulations" set-up by Ukraine's allies in the West (mostly the US and the UK), and it is my understanding that those war games were heavily taken into consideration as a basis for that counter-offensive decision. I'm not saying that the code behind those simulations was faulty, I'm just saying that software is already used at an operational level (at least) when it comes to war.

As per the sources, here's this one in The Economist [1] from September 2023, just as it had become obvious that the counter-offensive had fizzled out:

> American and British officials worked closely with Ukraine in the months before it launched its counter-offensive in June. They gave intelligence and advice, conducted detailed war games to simulate how different attacks might play out

And another one from earlier on [2], in July 2023, when things were stil undecided:

> Ukraine’s allies had spent months conducting wargames and simulations to predict how an assault might unfold.

It was mostly an old-school kind of wargames.

There was an article about a giant real 3D map in a room with all the commanders there discussing what each one has to do, contingencies, ...

The reason for the counter-offensive failure were multiple and complex, good or bad software would not have changed the result significantly.
